Abstract: A power supply device according to an embodiment of the disclosure includes a power supply unit including a first power supply unit transmitting standby power to an electronic device and a second power supply unit transmitting main power to the electronic device and a cable including a standby power transmission line transmitting the standby power to the electronic device, a main power transmission line transmitting the main power to the electronic device, a first detect line receiving a power-on signal for operating the second power supply unit from the electronic device, and a second detect line determining whether the power-on signal is received. The second power supply unit does not operate when at least one of the first detect line and the second detect line is opened and the power-on signal is not received. Moreover, various embodiment grasped through the disclosure are possible.

Abstract: Disclosed herein is a display apparatus having a quantum dot sheet to change color by converting the wavelength of blue lights, a middle mold having a middle supporting unit to support a front edge unit of a light guide plate, and a supplement member coupled to the middle supporting unit and configured to reflect the light radiated from the a source to prevent the light that is radiated from the light source from exiting through the gap between the light guide plate and the middle supporting unit, and thus the generation of bright line may be minimized and heat radiation performance may be enhanced.

Abstract: A display module and a display apparatus having the display module are provided. The display module includes a light guide plate which turns a path of generated light and emits the light through an emitting surface, a quantum dot (QD) sheet provided to correspond to the emitting surface to improve color reproducibility of the light emitted from the light guide plate, and at least one guide member which is fixed inside of a chassis and supports the light guide plate and the QD sheet. Using such a configuration, the color reproducibility of the display module may be improved, and the light guide plate and the QD sheet may be fixed together.
